Another bundle of issues from Coverity triage. The first one is in x86/mm, and looks scarier than it is. The others are all in xen/drivers and AFAICT are pretty minor. Cheers, Tim.

Future AMD SVM supports a new feature called flush by ASID. The idea is to allow CPU to flush TLBs associated with the ASID assigned to guest VM. So hypervisor doesn''t have to reassign a new ASID in order to flush guest''s VCPU. Please review it.

Keir, pci-detach triggers IO page table deallocation if the last passthru device has been removed from pdev list, and this will result a BUG on amd systems for next pci-attach. This patch fixes this issue.

Hi Ian, There have been a lot of interest on gfx passthru recently. This patch enables ATI VBIOS in passthru mode. The guest VM system BIOS (including Windows boot logo) can now show in passthru screen. We have tested with various Windows and Linux guest VMs. Please help review it. We are also looking forward to comments and suggestions from Xen community users. Signed-off-by: Wei Huang

This patch set adds basic supports for amd next generation iommu (IOMMUv2) hardware. IOMMUv2 supports various new features advertised by iommu extended feature register. It introduces guest level IO translation and supports state-of-the-art ATS/ATC devices with demand paging capability. Please refer to AMD IOMMU Architectural Specification [1] for more details. Thanks, Wei [1]

Hi all! I''m very interested with XenVGAPassthrough and tries to do it on my system with vt-d support: CPU: Intel core2duo E8400 MB: Asus p5q-vm do mem: 8GB So I''m succeed at Intel IGD: 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) with Debian Sid''s XEN 4.1/Linux 2.6.39-rc7+ (from git://

Using "par" seems easily put a "hist" and a density side by side on the same output window. I would like to use some features in "histogram" from Lattice, but how can I put "histogram" and "densityplot" side by side on the same graph?

I have a plot of cumulative distribution function which is a step function, I'd like to put a cycle at the right end of each line to indicate that the value here is not available in this line.

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.

Hi, The following 4 patches enable direct device assignment (PCI passthru) for HVM guest on AMD IOMMU platforms. Please apply them against C/S 16491 as the named order. To enable AMD IOMMU, please add "enable_amd_iommu" as xen boot parameter. 1-cleanup.patch: code cleanup, bug fix, minor enhancements to existing amd-iommu codes. 2-passthru-amd.patch: passthru support, modifications to

Hi, I am running the following example which can be found on page 12 of the pdf file of COIN package wt<-wilcox_test(pd~age,data=water_transfer,distribution="exact", conf.int=TRUE) "wt" actually contains the estimate of difference in location and the confidence interval of it. I am just wondering how can I extract these values? From the examples, I understand that the

Hi, Two functions wilcox.exact and wilcox_test give slightly different confidence intervals of the difference of the medians: for example y<-c(0,0,1.081,0.594,0,0.769,0,0.009,0,0,0.798,0.405,0.498,0.946,1.35,1.149,0.528) x<-c(rep(1,10),rep(2,7)) aa<-wilcox.exact(y~x,conf.int=TRUE) bb<-wilcox_test(y~factor(x),distribution="exact",conf.int=TRUE) aa bb Does anyone know

Does anyone know why wilcox.exact gives W-statistic 6 instead of 12 as indicated below. 12 is the rank sum of group 0 of x, which is the linear statistic computed by wilcox_test. y<-c(1,2,3,4,5) x<-c(1,1,0,0,0) (a) wilcox.exact wilcox.exact(y~x) Exact Wilcoxon rank sum test data: y by x W = 6, p-value = 0.2 alternative hypothesis: true mu is not equal to 0 (b) wilcox_test

The data set has a number of variables each of which is classified into two groups. For each variable of each group, I need to create a histogram. All the histograms are to be lined up into a file that looks like group1 group2 Variable 1 Histogram histogram Variable 2 Histogram histogram ........................... Can you give me a hint as to what

Hi Jan, Attached patch dumps io page fault flags. The flags show the reason of the fault and tell us if this is an unmapped interrupt fault or a DMA fault.
